Lantern.



oneven vmnnnnsriasnn, or CHICAGO, ILLnois.

Y Beitflnovvn-th-at LfGnovnn' W'. HELL- ;szriiaivn, a vcitizen of thev United States, re-

siding 'atr Chicago, in the countyof Cool:

and" atebf Illinois, have invented acer t' in ein yand useful Improvement in Lanterns', 'f'which the following is a full', clear,

:co oise, and exact description, reference be- {ingjllad VAto. the .accompanying drawings,

i 'foi-iningya party of this specification.

ll/l'y iiivention'relates to lanterns, and con- .templates suoli acdevice which includes self- ,.contained gasfproducingapparatus.

'able lanterns are ordinarily subjected.

',Cflie devicecof my invention-'has .palticus larutility as a' lantern which is adapted to beca-rr'edl'aliont end-'the particular 'type ivliieli l have primarily in mind is the raile f road type of lantern, 4v vhei'e the .lantern glob/eis surrounded by a protecting cage.

, It is the further 'object of my invention to' provide 'a vsimple and elic'ient vdevice and," further, to provide a device which will be strong and durable and which will Withstand the usual hardusa'ge to which port-- lt ,is a further object of my invention to provide elementsl which are 'necessarily involved in a gas 'lantern'ivhich will be in lsuch forin that they may be. applied to the standard types of oil lanterns, and l have drawn some of the appended claims with this idea in view. L u

ln the accompanying drawing Figure l is sin elevationalv vievv thereof, parts being broken away and shown in section in order to clearly reveal the interior construction, and Fig. 2 is a detailed View, which Will be referred to.

The protecting cage 'of my device is illustrated at 3, and comprises vertical and horizontal Wires, secured together at the intersections by means of joining pieces 4. The Wire of these ,cages is of substantial diameter and-'a fairly heavy and sturdy inclosing structure is secured. The cage terminates at- Y the lower end in a base ring 5, and an intermediate ring Gis provided.

A globe 7 of glass is mounted upon the intermediate ring 6.- v

A disk 8, preferably of metal, is disposed on the top of the globe 7 .and this disk is cut out, as illustrated, in Fig. 2, in order to provide the protectedoutlet openings 9, 9

for the exitof the products of combustion, it being iimdei'stood, of coni-se, that the globe has an air entrance below.

A easing l0', preferably of metal,is passed over the top of the lobe and the disk, as

clearly illiistrated. his casing is provided with .a transverse partition 11 and a coin l pression spring l2 isldisposed between the partition and the dislrv 8in order to iirmly' clamp'the dist: in place. i

Below the partition the 'circular ivall of the casing ll) is provided with slots 13, l"

for the exit of waste gases. An annular canopy lli is soldered, riveted or otherwise secured to the circularivall of the casing l0 and theupwardly-extending,strands of the cage are attached firmly to this canopy'. The result is that the parts which have been described, are all securely fastened together. .f/Tli'e-casing l() is provided Witlia-cover l5 and this closes agasrproducing compartment 16. ,v 4

At least one of the vertical members of the cage is made tubular, and l have illus At the trated this tnbular member at 8a. bottom this member is extended below and then up intothe globe l Whereit is provided with a burner l?.` This special piping is connected with a pipe 18 which extends through the Wall of the chamber l0 and up to the top of the gas-producing chamber 16, and the bottom of this pipe is joined to the member 3a by means of a union i9;

A hood 20 is screwed over the ltop of the chamber l() and this forms a Water chamber 2l for which an air inlet 22 is provided.

Some gas-producing material, such as calcium carbid, is disposed inthe chamber 16, as illustrated, andthe Water from the chamber above is fed thereto, foitlie provalve seat 26, Which has 'a central control v opening. This opening is governed by a needle 'valve 27 which extends from the not l tom of the Istein 25 and the stein 25 is provided Vwith a slot 28 Which admits Water at yall times to the valve seat, the position of the valve determining the opening in the valve seat. The stem is provided with 'a lrnuiled head Q9 on `the outside of the nood the purposes of' manipulation. ,ln order to protect the valve, 'afperorated protecting sleeve issecured upon thel top of the pairtition 1i and extends up aroundl the plug.

A It-Will now be'seen that. when the water' is admitted to the gasproducing chamber' the chemical reaction with the calcium car-A bid will result in the production of acetylene gas, which .then passes down the piping- 18, 3a to the burner 17, which is the proper burner, as is Well known in the art, for an acetylene flame.

t It will be understood that the 'foregoing is a description of a specic form of m invention, which I present so that those skilled in the art may beinstruc'ted in the use of my invention,

changes or modifications which may properly lie Within the -scope of the appended claims,

I claim:

-2l. In a lantern, a glohe,

openings therein disposed on the top of said globe, a gas producing` chamber disposed p and I contemplate any' a disk havingl over said diskya spring interposed between said gas producing and means for securingthe gas producing sill-amber to said gione to clamp the parte p ace. f v

2, In a lantern, a globe, a a gas producer on top pipe running fromsaid gas producer to a burner "in said globe, said pipe forming e part of said protecting cage.

3. In a lantern, a globe, a protectingcage,

protecting caffe,

ai gas producer `on top-of said globe, lsaidv producer having a chamber forcalium car bid'and al pipe running vfrom said gas producer to a burner in' said giobe,said pipe forming a part of said protecting cage.

In witness whereof, I hereunto subscribe my name this 29th day of May, D., 1913.
